Married couple killed in shooting, their teen son charged

We know what happened in a tidy townhome on Palmetto Street in southwest Houston. We know that Dawn Armstrong was killed in a deadly shooting and her husband, Antonio Armstrong, later died from his wounds. We know their teen son was charged in their murders. What we don't know is why.

Antonio, 43, was taken to Memorial Hermann Hospital - Texas Medical Center in critical condition with a gunshot wound to the head. He was pronounced dead later on Friday night.

People who knew Dawn and Antonio are stunned to learn about the shooting.

“It's incredible," said Pastor Scott Binkley "You can't get your head around it. We need a little time to digest it -- pray a little bit about it because it's stunning to say the least.”

After all, the couple and their children seemed like the perfect family. When police arrived at the home at around 3 a.m. Friday, they say they found no sign of a struggle, no sign of forced entry but no sign of family strife either. 

“Absolutely not," said Houston Police Department investigator Jimmy Dodson. "This was an outstanding family. The man was a hardworking breadwinner. He was an associate pastor in an area church, I'm not sure which one. He was a great guy.”

Antonio had played football with the Texas A&M Aggies. From there, he bounced around the NFL for a while before flourishing in the Canadian Football League. An injury forced him to retire. He and Dawn then opened multiple gyms.
